Magnetic-order-driven metal-insulator transitions in the quasi-one-dimensional spin-ladder compounds BaFeS and BaFeSe
Seulki Roh, Soohyeon Shin, Jaekyung Jang +9
The quasi-one-dimensional spin ladder compounds, BaFeS and BaFeSe, are investigated by infrared spectroscopy and density functional theory (DFT) calculations. We ob…
Optical signatures of phase transitions and structural modulation in elemental tellurium under pressure
Diego Rodriguez, Alexander A. Tsirlin, Tobias Biesner +5
A room-temperature infrared spectroscopy study of elemental tellurium at pressures up to 8.44 GPa in the energy range 0.015-2 eV is reported. Optical signatures of the high-pressur…
Two linear regimes in optical conductivity of a Type-I Weyl semimetal: the case of elemental tellurium
Diego Rodriguez, Alexander A. Tsirlin, Tobias Biesner +5
Employing high-pressure infrared spectroscopy we unveil the Weyl semimetal phase of elemental Te and its topological properties. The linear frequency dependence of the optical cond…
Detuning the Honeycomb of -RuCl: Pressure-Dependent Optical Studies Reveal Broken Symmetry
Tobias Biesner, Sananda Biswas, Weiwu Li +10
The honeycomb Mott insulator -RuCl loses its low-temperature magnetic order by pressure. We report clear evidence for a dimerized structure at GPa and observe the brea…
